which involves taking the walnuts from dan's farm and sun-drying them, shelling, grinding, and then roasting the nuts, all to enhance flavor. and the other secret to success? the walnuts, of course. >> well, it's simple. i mean, what we're doing is not only extracting the oil from the walnut, what we are trying to get is the flavor of the walnut in the oil, and that's really what makes the difference in the quality. so what we do is by roasting the nuts, you get the flavor really strong, and so the best walnuts you use, the best walnut oil you'll get. so dan, you know, using these really nice natural walnuts, is getting really... the flavor is great. well, i think until now, until we arrived here, they could only find that imported from france. so it was expensive. often it was a little rancid, too, because it was so-- you know, the time between the production time and, you know, it arrived here. so, you know, the fact that it's very fre, local, makes them, you know, even more excited. and to be local is important, too.
